We got to Siempre Sano for an afternoon lunch during our trip to PM and I wish we could have visited them a few more times! The food was sooooo good, and reasonably priced. The large option comes with homemade tortillas, soup, rice, beans, salad, a drink, dessert, and your choice of three fillers for just 80 pesos! On the day we were there they had a delicious seitan-based mock pork, vegetable soup and another spicy dish that I particularly enjoyed. Of course the homemade tortillas are like nothing you'll find in the USA, fresh and served warm. The staff were very friendly and spoke great English (much appreciated as I didn't have enough Spanish to convey everything we wanted). They wrapped up our leftovers for us and were happy to put together a take away order for a family member. If only they were open for dinner!
